Thanks, a few trivial comments:

001:
1)
PublicationRelation

+typedef struct PublicationRelation
{
NodeTag type;
RangeVar *relation; /* publication relation */
Node *whereClause; /* qualifications */
List *columns; /* List of columns in a publication table */
bool except; /* True if listed in the EXCEPT clause */
-} PublicationTable;
+} PublicationRelation;

Can we make comments more clear. Suggestion:

typedef struct PublicationRelation
{
NodeTag type;
RangeVar *relation; /* publication table/sequence */
Node *whereClause; /* qualifications for publication table */
List *columns; /* List of columns in a publication table */
bool except; /* True if listed in the EXCEPT clause */
} PublicationRelation;

002:
2)
+ if ((pubrelkind == RELKIND_RELATION && relkind == RELKIND_RELATION) ||
+ (pubrelkind == RELKIND_RELATION && relkind == RELKIND_PARTITIONED_TABLE) ||
+ (pubrelkind == RELKIND_SEQUENCE && relkind == RELKIND_SEQUENCE))

Can we optimize it to:
if ((pubrelkind == RELKIND_RELATION &&
(relkind == RELKIND_RELATION || relkind == RELKIND_PARTITIONED_TABLE)) ||
(pubrelkind == RELKIND_SEQUENCE && relkind == RELKIND_SEQUENCE))

3)
+-- Modify the sequence list in the EXCEPT clause
+ALTER PUBLICATION regress_pub_forallsequences3 SET ALL SEQUENCES
EXCEPT (SEQUENCE regress_pub_seq0);

After this or at the end, can we add a testcase for 'SET ALL
SEQUENCES' to cover the reset except-seq code-flow.

thanks
